Wildlife Identification Help

Over the years, there's been quite a few animals/plants that I've seen, but have subsequently remained unidentified. I have pictures of them, but am puzzled as to their ID. I'm wondering if someone may be able to assist me. I would greatly appreciate it. Some of these are really bugging me.

• A flamingo-ish heron-ish bird from Cayo Coco, Cuba
• A sort of ordinary-looking grey bird from Shenandoah Valley, Virginia
• Some sort of moth
• And a few mushrooms: this one, these ones, these ones and these ones.
• Some sort of shrew or vole, DOA
• The skin of some sort of Cuban snake from Cayo Largo. Perhaps some sort of grass snake? I'm not sure it will ever be able to be identified. But I'm hoping some Cuban snake expert who knows about Cayo Largo's snakes will happen to read this!

I'm sure there are some more. And there are a number of un-IDed creatures that I haven't listed here, because I simply haven't even looked into them yet and am thinking they may be easy to identify.
